"Yes," she whispered urgently. "I'm so hot. You're so fucking big!"

He continued fingering her clit, now several fingers playing inside her at once. Suddenly, she let go of his erect cock and arched her back. She let out a stiffled scream and threw her head back.

"Je-sus!" she whimpered, trembling from head to foot.

He smiled, practically feeling her orgasm himself. That's it, baby, he thought to himself. Now you're nine. All fucking mine! He thought of his younger brother Steven, who was Susan's age and also a virgin. Both brothers had always been intensely jealous of one another, and Mark knew what Steven had been thinking ever since Susan had arrived at their parents' summer cottage two weeks before.

They were the same thoughts he had had, the only difference being he had fucked girls before. He knew exactly what to expect. And that keen expectation had further heightened his anticipation. He had wanted Susan more than any girl he had ever had before. Cousin or no cousin!

God, he thought. If Steven saw us now he'd kill me! Too bad, kiddo!

Susan lay cradled in his arms, gazing with adulation into his eyes.

"Oh, Mark, I can't tell you. Wow… that felt so good. So much better than when I do it!"

Without saying another word, he took his cock in his hand and guided it to the girl's virgin cunt. Then he slammed forward.

"Jesus!" she cried out, her legs automatically wrapping themselves around his waist. "So fucking big!"

She thought he had split her in half. She felt something burst inside her.

She felt his crushing weight on top of her, flattening her tits and she wondered if her mother had been right after all. At first there was only pain, not the sudden onrush of unbelievable pleasure she had just experienced. But the pain soon turned to the red hot bursts of sheer ecstasy as his cock seemed to swell and grow inside her.
